NOTE**** The Powercab has no dedicated supply for the Cab Bus. This means that the cab bus power is power is subtracted from total system power.
If your layout has a TOTAL cab bus longer than 30 feet you will need more cab bus capacity. If your total usage of the cab bus exceeds 1 amp you will need more cab bus capacity. To learn about adding extra power to the bus at about 30 foot intervals, go here for the parts needed on cab bus power injection. The overall goal is this: A minimum of 8v DC as measured on the UTP Panel and cab bus cables between pins 2 and 5 / Black and Yellow.
If you do not own a multimeter here is a link to an inexpensive one from Home Depot - http://www.homedepot.com/p/Powerbuilt-Digital-Multi-Meter-648349/204505225
